propose them as zinc binders for the inhibition of human carbonic anhydrase (hCA) enzymatic activity. Synthesised compounds were tested against four hCAs (I, II, IX, and XII) revealing a promising submicromolar inhibitory activity characterised by an isozyme selectivity pattern. Structural modifications explored within this scaffold are: presence of an aryl ring on the sulphonamide, p-substitution of
抽象的 设计,合成并充分表征了一个大型的基于纤维状的N-酰基磺酰胺库,以便将它们用作抑制人碳酸酐酶(hCA)酶活性的锌结合剂。对合成的化合物针对四种hCA(I,II,IX和XII)进行了测试,揭示了以同工酶选择性模式为特征的有希望的亚微摩尔抑制活性。在该支架内探索的结构修饰为:磺酰胺上存在芳基环,该芳基环的对位取代,苯并噻唑或二苯甲酮作为核心核,以及一个n-丙基链或Cα碳上的双甲基二甲基。生物学结果与分子模型分析非常吻合,揭示了hCA I,II和IX活性位点中与锌离子的直接相互作用。这些发现支持了对较少研究的仲磺酰胺作为潜在的hCA抑制剂的探索。
